This framework aims to deepen the understanding of country teams to clarify their engagement in leveraging policy, institutional and behavioural change for achieving positive policy, institutional and human behavioural changes necessary to meet resilient food systems objectives. It provides an outline of the fundamental elements in the design and implementation of an advocacy strategy including understanding decision cycles and influence for sustainable land management and agroecological systems; shares experiences reflecting different scales of intervention (national, sub-national, local); and provides examples of how different mechanisms such as multi-stakeholder platforms can be used as an engine of socio-ecological change.
